Composition and method for controlling harmful arthropods

Abstract

The present invention provides a composition for controlling harmful arthropods having an excellent control efficacy on harmful arthropods. A composition for controlling harmful arthropods comprising a carboxylic acid compound represented by a formula (I); wherein each of symbols are the same as defined in the Description; or salts thereof and at least one kind of neonicotinoid compounds selected from the group (A) consisting of imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, thiacloprid and nitenpyram, shows an excellent controlling efficacy on harmful arthropods.

The invention claimed is: 
     
       1. A composition for controlling harmful arthropods comprising a carboxylic acid compound represented by a formula (I): 
       
         
           
           
               
               
           
         
         wherein
 n represents an integer selected from 1 to 5; 
 R 1  represents a halogen atom, a hydroxy group, a nitro group, a C1-C6 alkyl group or a C1-C6 alkoxy group; and 
 when n represents an integer selected from 2 to 5, each R 1  may be the same or different; 
 
         or salts thereof, and 
         at least one kind of neonicotinoid compounds selected from the group (A) consisting of imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, thiacloprid and nitenpyram, 
         wherein a weight ratio of the carboxylic acid compound or salts thereof to the neonicotinoid compounds is in the range of 10:1 to 1:10. 
       
     
     
       2. A method for controlling harmful arthropods which comprises applying an effective amount of the composition for controlling harmful arthropods according to  claim 1  to harmful arthropods or a place where the harmful arthropods live. 
     
     
       3. A method for controlling harmful arthropods which comprises applying an effective amount of the composition for controlling harmful arthropods according to  claim 1  to plant seeds. 
     
     
       4. The method for controlling harmful arthropods according to  claim 3  wherein the plant seeds are seeds of corn, cotton, soybean, beet, rapeseed or rice.
